  NAME

    protocols - protocol name data base

  DESCRIPTION

    The protocols file contains information about the known protocols used in
    the Internet. For each protocol, a single line should be present with the
    following information:

    official_protocol_name   protocol_number   [alias(es)]   [#comment]

    Items are separated by any number of blanks, tab characters, or both. A
    pound sign (#) indicates the beginning of a comment; characters up to the
    end of the line are not interpreted by routines that search the file.

    Instead of the UNIX etc/protocols file, you have the Windows
    %windir%\system32\drivers\etc\protocol file. The %windir% variable
    represents your Windows installation directory.

  FILES

    %windir%/system32/drivers/etc/protocol
        Provides protocol name-to-protocol ID resolution for Windows Sockets
        applications.
